Execution: 4-acetyl-1-methyl-cyclohexene 1) was placed in the flask and mixed with the sulphuric acid/ethanol mixture 2) at room temperature for about 0.5 hours while being stirred and in conditions that exclude moisture. Component 3) was then added during the course of about 1 hour. The allyl alcohol (component 4) was added portion by portion. The mixture produced in this way was transferred to a steel autoclave insert and heated to 190° C. for 5 hours under 20 bar nitrogen. The GC control showed that the educt had been reduced down to 2% and that 31.5% main product had formed.
